The Asics Men's Gel-Kinsei 4 Running Shoes is the brand’s most innovative top-of-the-line running shoe to date. Improving and reducing the weight of existing technologies to improve the shoe’s overall performance was the focus for the fourth version of the Gel-Kinsei. The result is notable with almost a full ounce being shaved off from the previous model taking the shoe from 12.8 ounces to a lightweight 11.9 ounces. This re-engineering also includes a redesigned Heel Clutch Counter System™ replacing the internal heel counter with an external Clutch Collar™ resulting in less heel slippage; redesigned fore-foot tooling, which is now decoupled to create five separate pods, providing better flexibility and more cushioning; and, reduced synthetic reinforcements and overlays in the upper, enhancing the comfort and fit. The shoe will continue to use Cuprothermo™ mesh in the upper, which helps temperature control of the foot by retaining heat in cool weather and releasing it in hot weather.
